There seems to be overspray on my car (or something that closely resembles that) and i have tried everything i can think of to get it off with no luck. I have tried a walmart bought meguiars claybar (which i have heard might not be the best) but it takes some of it off or it at least appears to, when i rub it with the claybar the claybar is getting black on it, but the stuff is still on the paint. Anyway, what can you guys recommend to me that would be safe for my paint to get this stuff off?
